Imagine if Metroid games started out without Samus responding to a distress call. Exactly what would drive the story? That's the bottom line in this case.
I'd have to agree with Hostile, Nintendo's games involve some of the most immersive gaming universes out of any games. I'll pick up a PS2 game (like Ratchet and Clank) and I'll play it: Sure it's fun, but I don't feel any need/want to keep going. I end up playing for, say, 45-60 min and put the game back down because it doesn't interest me the way Nintendo's universes do.
And I know this point has been brought up (or at least I thought it has), but what I find really ironic is that IGN is the same site that praises and seems to fawn over games like Halo 2, GTA:SA, etc. Other games that do exactly what this article seem to point out and criticize Nintendo for. I mean, the review for GTA:SA gave it a 9.9 and called it the best PS2 game ever. Now what kind of message does that send to other developers that look to Rockstar:
"Oh, if they can develop the same game 5 times and still get raving reviews like that, let's do that then"
And then as soon as Nintendo makes an incredible game such as Paper Mario 2, then they get jumped on because they don't have enough innovation, and when they do they just use old franchise mascots? What the hell?
Sure the editorialist can pine for new games from Namco and Sega instead of co-developing Donkey Konga and F-Zero, and I respect that. But, Nintendo is certainly providing, what I consider, a good equilibrium between new gameplay and old experienced that are revitalized.
